1Preheat the oven to 220 degrees Celsius. Peel the potatoes and cut them into halves. If you have large potatoes, cut them into thirds or even quarters.
2Place the cut potatoes into a large bowl and add in your chicken thighs. Add a big glug of olive oil, 1 tablespoon of salt, ¾ tablespoon of dried basil, ¾ tablespoon of paprika, ¼tablespoon of chill flakes, and ½ tablespoon of garlic powder. Mix well so both the chicken and potatoes are well coated in the spice mix.
3Pour your chicken and potato mix into an oven-safe dish. You want to make sure everything is evenly spread for cooking. Place into the top rack of your preheated oven. Flip halfway through cooking time.
4Prepare your sauce as the chicken and potatoes cook. Grate 1 whole cucumber and season with a ¼ tablespoon of salt. Allow this to rest for 20 minutes at which point you should start to see a lot of water separate from the cucumber. Drain this excess water as it will lead to a runny sauce.
5Mix your drained and grated cucumber with 4 heaping tablespoons of greek style yoghurt, a big pinch of salt, some black pepper, and the juice of half a lemon. Mix well to combine and refrigerate until ready to serve.
6At around 50 minutes you can start testing for the doneness of your chicken and potatoes. You want your drumsticks to be fully cooked through, with an internal temperature of 175 degrees. Your potatoes should be easily pierced with a butter knife at this point. Once everything is cooked through, remove from the oven and allow to rest for 5 minutes.
7Serve each plate with a healthy portion of potatoes and a chicken drumstick. Finish each plate with a scoop or two of your greek style sauce and a slice of lemon. Enjoy!
